I have a Lenovo T410, and I would like to use the SysRq key, but whenever I press the Alt+SysRq+letter combination, I keep getting the print screen dialog in linux.

Is there a way around this? I have tried pressing Ctrl+Alt+SysRq+letter as well as Fn+Ctrl+Alt+SysRq+letter but to no avail for any of these. Any information to get around this would be great.


It's not the same for all laptops unfortunately, but the general idea is to consult the manual to figure out the SysRq and then use Alt in addition to that, for example this is Lenovo X1:

Lenovo X1 Carbon user manual mentions SysRq is Fn + S, I managed to trigger SysRq combination using the following sequence:

  • Press and hold Fn + Alt + S
  • Release both Fn and S
  • Press and release the desired key (e.g. h to show the SysRq help)
  • Release Alt

On most laptops (I haven't verified on the T410):

  • Press and hold both Fn and Alt.
  • Press and hold SysRq.
  • Release Fn, and optionally Alt (but keep SysRq down).
  • Press the letter or other key.
  • Release everything and massage your sore fingers.

This holds for desktops as well: you can release Alt after you're holding SysRq, that way you only need to hold two keys at a time.

  • In my HP i do: Alt Fn SysRq (release Fn) (release SysRq) (release Alt) – LatinSuD Sep 10 '13 at 11:05
